I just searched "Ruby Sieve of Eratosthenes" and "go Sieve of Eratosthenes". The language ruby was the focus of the first four results, and after that some were ruby-specific and some were just Sieve with a mention of ruby somewhere. Exactly the same applied for Go. The first four were Go-specific, and the remainder were a mix of Go-specific and pages about the Sieve with "go" somewhere on the page. Also, as others have said, one immediately comes across references to golang everywhere.
